Rivers snipes upstream, not downstream. Liking KISS in 1986ish wasn’t practically cool and D&D at the time was probably less cool than KISS. However, would either shock you in regards to what a 16 year old Rivers was into at the time? To me, nothing in Rivers persona reeks of being the cool kid, so I’ve always likened this to a “safe space” song. The guy was in shadows of KISS posters and rolled 12s because a DM told him to. “The Garage” is where he made himself into who is.
